IMO, if the ID card thing had been introduced in, say, 2000, the opposition to it would probably have come from the Right. That 'mark of the beast' business. The Right has a long history of objection to national IDs.

But criticism of the system is now coming from the Left. In the current political situation, I can kind of see why.

Modern technology will eliminate the old idea of privacy. It's pretty much unavoidable. The task will be to implement it in a way that ensures minimal abuse and maximizes safety. I don't trust the current administration to do this. I do trust the moderate middle of America to reassert itself. That is also inevitable. (IMO)
